It seems like nobody here has experience with it. I asked about it some time ago but no one answered.
I have a small tree of co-op 43 but will have to wait at least 2 more years for fruit, I can let you know then.
Being a club release, you are are unlikely to find a tree or scionwood. It doesn’t have a US plant patent filing that I have found so you would could propagate it if you got scionwood. It is in the USDA GRIN collection but scionwood is not available to order .https://npgsweb.ars-grin.gov/gringlobal/accessiondetail.aspx?id=1522587.
There are a number of European filings under either Coop 43 or Juliet but I’m not familiar with what protection status those give.
I got it from a friend in France (I am in Europe). I asked about this apple here some time ago and thought there will be people familiar with it. It’s from US and not exactly novelty but it’s virtually unknown which surprised me.
I think it will be next to impossible to get it in your country now when they made it club variety in Europe. Very unfortunate indeed. I read somewhere it’s nothing special tastewise but the keeping ability and resistance might make up for it.
